We speak of the greatness of God, but He also speaks of the greatness of His people,
“Bring out the blind people who have eyes, and the deaf who have ears. Let all the nations be gathered together, and let the people be assembled. Who among them can declare this, and show us former things? Let them bring out their witnesses, that they may be justified; or let them hear and say, ‘It is truth’” (Isaiah 43:8-9).
God has spoken through His prophets in Israel and the apostles in the church. What other nation or group can do such a thing?
